On Wednesday, Apple released its 2009 Aluminum Keyboard Firmware 1.0 update for the 2009 Apple Wireless Keyboard. The update, a 1.1 megabyte download, improves battery performance of the device when used in combination with other Bluetooth devices. The keyboard must be connected or paired to perform this update. The update package will install an updater application into the Applications/Utilities folder and will launch it automatically.

As always, the update can also be located and snagged via Mac OS X’s Software Update feature.

The updater requires Mac OS X 10.5 or later running on an Intel-based Mac to function.
